1. Kierowca samochodu jadącego ruchem jednostajnie opóźnionym z prędkością V0 = 25 m/s nacisnął hamulec i zmniejszył prędkość do V2 = 15 m/s w ciągu t = 20 s. Oblicz wartość przyspieszenia samochodu. 2. Motocyklista jechał ruchem jednostajnym prostoliniowym z szybkością 54 km/h. Przebył tę trasę w czasie 30minut. Oblicz jaką drogę przejechał motocyklista.

3. Autobus ruszył z przystanku ruchem jednostajnie przyspieszonym z przyspieszeniem o wartości 2 m/s². Oblicz drogę autobusu po 5 s.

Bardzo proszę o pomoc i dziękuję ślicznie z góry!
